The LS Pro, KuroPro and every Marvell SoC device that Melco/Buffalo/Revogear is currently producing come with UBoot. LinkStation and Kuro devices prior to the LS Pro had a rather non-descript and less flexible bootloader. Linux-not-Included ported UBoot over to these older devices, so that now all of the boxes that we we work with here have access to this increased flexibility.
